T2Edge for HDc is standard-based solution that enables the delivery of DVB-T2 regional or local services over SFN networks while saving operating OPEX by optimizing the distribution network bandwidth.

Applications

DVB-T2 regionalisation

DVB-T2 ultra-local insertion

Regional Emergency Warning Services (rEWS)

Highlights

Deployed in the DVB-T2 world’s largest roll-out

In 2011, MULTICHOICE, the leading multichannel digital television operator across the African continent, has selected the T2Edge for the deployment of the world’s largest DVB-T2 network over Pan-African countries with a total bouquet of more than 50 different channels in various languages over 15 countries. Since then, it has been deployed by leading TV operators across Africa, Asia and Europe.

Regional content insertion using PLP substiution

The T2Edge is taking benefit from the multiple PLP technology to build the DVB-T2 regional multiplex at the DVB-T2 transmitter sites. Receiving national and regional T2MI streams composed of several PLPs, the T2Edge can substitute in the national T2-MI stream some PLPs from the regional PLPs to update with local content. The insertion is performed in a deterministic manner to enable SFN broadcasting

Regional content insertion using PLP aggregation

The PLP aggregation technology is an advanced and flexible regional content insertion solution that behaves as a PLP remultiplexer. It allows aggregating one or several PLPs between the national and regional T2-MI stream to build the regional multiplex. In some region, the T2Edge may aggregate 3 PLPs while in another regions, it will create a multiplex composed of 2 PLPs. In each region, the T2Edge guarantees the broadcasting over SFN networks.

Bandwidth optimization to reduce annual OPEX

The use of Multi-PLP architecture and PLP Substitution brings unmatched flexibility to the Network Operator and allowing a drastic reduction of the operational costs; all common TV content (national or international) being delivered only once to save the distribution network bandwidth.

Regional Emergency Warning Services (rEWS)

ENENSYS patented technology (rEWS) is a receiver-agnostic system providing video-based emergency warnings on a regional basis of dangerous weather events and natural disasters for DVB-T2 networks. T2Edge with rEWS allows normal programming to be interrupted to play out the emergency alert, replacing all the normal A/V transport stream components with the emergency alert A/V content.

High Density chassis

The T2Edge operates at the edge of the DTT network on the transmission sites where density and power saving is vital. The T2Edge can be embedded in the ENENSYS high density chassis to allow the generation of 6 different regional DTT multiplex. It can also be combined with TxEdge, ASIIPGuard or IPGuardV2 products
